These are courses, conferences and talks that you can buy to help us raise the funds needed.


BrazilJS—the universe's biggest JavaScript conference—is also helping Leo in his battle! Everyone who buys from the early bird "Konarzewski" batch until 10/05 will help in his treatment: R$50,00 from the ticket price will be donated to the campaign!

The event will take place in 21/08 and 22/08, in Porto Alegre - RS, and will gather highly skilled people from the JavaScript community. You can't miss that out!

NEJS Hackathon 2015

The folks from NordesteJS are organising the 1st Northeast JavaScript Hackathon, which will take place on 04/07 and 05/07, at the Universidade Federal do Rio Grande do Norte!

The ticket is only R$30,00, and all money will be donated to Leo's fundraising. And on top of that, you'll get to know the people from NeJS community, will learn something, and share your knowledge!

Devs pelo leokz

In partnership with Eventials we organised an online conference with many Brazilian developers.

Those who couldn't see the live transmission can still contribute! For R$50,00 only, you'll have access to the presentations recordings, and will be able to help Leo! All raised funds will still be redirected to Leo's fundraising!

Creating a static web server from stratch (and something more)

Let's see how simple creating a static web server is. It'll take us 5 minutes. Then, I'll explain how the automated deploy system that we use on ZOFE works (which uses the same static server, with the help of Travis CI, GitHub, scripts, and a few friends).

Organising your JavaScript in 5 steps

The terms "architecture" and "modularisation" may give you the impression that maintaining an organised JavaScript code requires planning, too much time, and too much refactoring. However, with some good practices, it's possible to improve your application's code without big redesigns and months of work. In this presentation, I'll show you how to start organising your JavaScript right away, in 5 steps, with no headaches.

WTF Oriented Programming

You can't always start a project from scratch (green field), and sometimes we have to maintain other people's code (brown field). It wouldn't be so bad to keep it going forward if the code was at least clean, readable, organised, and with tests. But sometimes we find a few gems that make us think: WTF!?!? Let's see some real life examples in this presentation.

Visual consistency in web projects

CSS is easy to modify, but very hard to maintain and test. This presentation's idea is to share a series of techniques and tools that help us guaranteeing a web project's visual consistency.

HOWTO courses
